For a long time, the water meters are usually installed outside of the South, some mounted on the wall of the building, installation of water meter hole in the ground, has no uniform standard for the installation. Groundwater table covers are lighter can not withstand the vehicle rolled erosion, much less tolerate cold weather test, especially in recent years, the La Nina weather phenomenon, resulting in Jiangnan region temperature normal cool, frequent water frost damage.

Water meter installed taking into account safety and convenience, should not be installed in sensitive to freezing and exposure conditions, should be installed in a closed solid, dry-and sediment pollution, prevent water erosion-proof vehicles rolling sites, so as to further improve the quality of water services, resolving the contradiction between water supply and charges, avoiding unnecessary waste.

Therefore, the unified houses under construction when a water meter installation environment, relevant departments as soon as possible a clear design standards, introduction of specification for installation of House in a well designed and built a margin for piping or equipment. Water meter installation planning for routine inspection and maintenance, as well as frost damage and facilitate unified meter reading and management. Existing and underground water meters will be installed on the wall reinforcement and protection work, add strong durable wall water meter protection box, reinforced surface water table covers, in cold weather before the water companies should unify the bandage cold warm outdoor water meter equipment, increase the security level.
Remote water meter installation, to pay attention to these matters. Such as winter frost, best signal transmission area can open, and user-friendly as possible and water Division.
